5. FOR VEHICLES EQUIPPED WITH POWER WINDOW CONTROL SYSTEM
When the battery is disconnected or the power to the window regulator motor is cut, the power window con-
trol system does not operate. It is necessary to initialize the system in the following procedures. Otherwise
window cannot be operated normally.
(1) Close window to the highest position.
(2) Keep holding the switch for 5 seconds.
(3) Check that automatic operation works. If not, repeat the above procedures.
6. FOR VEHICLES EQUIPPED WITH SLIDING ROOF SYSTEM
Sliding roof stop position might be required to be initialized when battery failures (such as battery disconnec-
tion, connector disconnection and the voltage drop) are detected while the system is in operation. This also
occurs when rotating the motor with the battery disconnected. Sliding roof initialization can be done by the
following procedures.
(1) Operate the roof up to the maximum tilt position.
(2) Release the switch, and push it again in the same direction. (After 10 seconds have elapsed,
initialization begins.)
(3) The roof starts automatic operation if holding the switch, completes full one cycle (tilt down, slide
open, slide close and tilt up) of travel. Do not release the switch until the roof stops.
(4) Check that the roof stops at the correct position.
7. FOR VEHICLES EQUIPPED WITH BRAKE PIPE FIT-
TING OF NEW STANDARD
A flare shape of a new standard is used for the brake pipe fitting
from this changed models.
NOTICE:
When ordering or replacing the parts, please be sure
to check and use the fitting of the same flare type.
Do not over–tighten them more than the standard
torque.
Torque: 15 N·m (155 kgf·cm, 11 ft·lbf)

VIBRATION METHOD: When vibration seems to be the major cause.
CONNECTORS
WIRE HARNESS
PARTS AND SENSOR1
Slightly shake the connector vertically and horizontally.
Slightly shake the wire harness vertically and horizontally.
The connector joint, fulcrum of the vibration, and body
through portion are the major areas to be checked thorough-
ly.
Apply slight vibration with a finger to the part of the sensor
considered to be the problem cause and check that the mal-
function occurs.Shake Slightly
Swing Slightly
Vibrate Slightly
HINT:
Applying strong vibration to relays may result in open relays.

3. SYMPTOM SIMULATION
The most difficult case in troubleshooting is when there are no problem symptoms occurring. In such cases,
a thorough customer problem analysis must be carried out, then simulate the same or similar conditions and
environment in which the problem occurred in the customer’s vehicle. No matter how much experience a
technician has, or how skilled he or she may be, if he or she proceeds to troubleshoot without confirming
the problem symptoms he or she will tend to overlook something important in the repair operation and make
a wrong guess somewhere, which will only lead to a standstill. For example, for a problem which only occurs
when the engine is cold, or for a problem which occurs due to vibration caused by the road during driving,
etc., the problem can never be determined so long as the symptoms are confirmed with the engine hot condi-
tion or the vehicle at a standstill. Since vibration, heat or water penetration (moisture) is likely cause for prob-
lem which is difficult to reproduce, the symptom simulation tests introduced here are effective measures in
that the external causes are applied to the vehicle in a stopped condition.
Important Points in the Symptom Simulation Test:
In the symptom simulation test, the problem symptoms should of course be confirmed, but the problem area
or parts must also be found out. To do this, narrow down the possible problem circuits according to the symp-
toms before starting this test and connect a tester beforehand. After that, carry out the symptom simulation
test, judging whether the circuit being tested is defective or normal and also confirming the problem symp-
toms at the same time. Refer to the problem symptoms table for each system to narrow down the possible
causes of the symptom.

1. CHECK FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the oil
reservoir.
If necessary, add fluid.
Fluid: ATF DEXRON II or III
HINT:
Check that the fluid level is within the HOT LEVEL range on the
reservoir / reservoir cap dipstick.
If the fluid is cold, check that it is within the COLD LEVEL range.
(c) Start the engine and run it at idle.
(d) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80C (176F)
(e) Check for foaming or emulsification.
If there is foaming or emulsification, bleed power steering sys-
tem (See Pub. No. RM599E on page SR–5).
(f) With the engine idling, measure the fluid level in the oil
reservoir.
(g) Stop the engine.
(h) Wait a few minutes and remeasure the fluid level in the oil
reservoir.
Maximum fluid level rise: 5 mm (0.20 in.)
If a problem is found, bleed power steering system (See Pub.
No. RM599E on page SR–5).
(i) Check the fluid level.

NOTICE:
If the glow plug breaks, the ECU detects the breakage and stops the automatic operation, so
the burner heater does not activate. (For other failures, similarly activated.)
The cause of failures (such as voltage malfunction, overheating malfunction, short–circuit or
breakage of functional componects, etc.) and how to remedy are shown by connecting the DTC
tester and reading the DTC.
1. OPERATION
(a) Connect the DTC tester between the connector A (Vehicle harness) of DTC check harness and con-
nector B (Power heater harness).
(b) Start the engine.
(c) Pressing the DTC calling button displays a 3–digit number DTC.
